Patent GB-1109176-A (GB)
Title: Improvements relating to strain gauge load cells
Inventor: SANDERS LEONARD
IPC: G01L1/16
Filed: 1964-08-15
Abstract: 1,109,176. Load cells. W. & T. AVERY Ltd. Aug.12, 1965 [Aug. 15, 1964], No.33402/64. Heading G1N. In a load cell including an elastic member 13 carrying at least one electrical strain gauge (not shown) the other parts of the load cell are arranged to stress the elastic member 13 so that the strain gauge always acts on a linear part of its characteristic. In the embodiment shown 18 is a cylindrical member to which are clamped end members 14 which compress member 13. If the elastic member is rigidly connected to end members 14 it may be placed in tension. In another embodiment the elastic member is placed between two sides of a rectangular frame, the sides being forced apart to allow insertion of the elastic member and then released. The prestressing force is greater than the sum of half the maximum stress to be applied to the cell and the stress which must be applied to the elastic member before non-linearity becomes negligible. Temperature compensating gauges may be provided and connected with the active gauges in a bridge circuit.

Title: Process for preparing multi-component nuclear fuels
IPC: G21C3/62
Filed: 1968-07-12
Abstract: 1,159,520. Nuclear fuel. W. R. GRACE & CO. 12 July, 1968 [25 Sept., 1967], No. 33452/68. Heading G6C. A process for preparing a nuclear fuel comprising the oxides of at least two actinide metals consists in contacting porous microspheres of a fertile material with a fissionable material in fluid phase to impregnate the microspheres, and then converting the fissionable material to insoluble form. This process may be accomplished by impregnating the microspheres with a sol or with an aqueous solution of a salt of the fissionable component followed by conversion to the oxide in the pores of the matrix by sintering. The microspheres can also be impregnated with the additive in gaseous form, e.g. PuF 6  or UF 6 . The fertile matrix materials may be natural or depleted urania (U-238) alone or in admixture with thoria; alternatively, thoria may be used alone. The fissionable component may be urania (U-233 or U-235) or plutonia.

Filed: 1974-07-30
Abstract: 1441048 Film transport control: automatic control of loop size BELL & HOWELL JAPAN Ltd 30 July 1974 [30 July 1973] 33551/74 Headings G2E and G3R In a motion picture camera having mechanism for moving the film intermittently through an exposure station and continuously through a sound recording station by separate motors, the arrangement is such as to form a film loop between the two stations, with a film position sensor connected to an oscillator circuit and formed as a h.f. coil, the coil being responsive to changes in the size of the loop which cause a change of impedance in the coil, so controlling the intermittent movement mechanism as to maintain the loop size constant. As shown, the film 10 passes through the exposure station 14 on to a sound recording station where it is drawn at a constant speed past a recording head 32 by a capstan drive 36. Between the two stations it forms a loop 40, against which rests the end 48 of a detector lever 44 biased by a spring 50. The detector has a soft-iron portion which cooperates with a sensor 52 formed as a h.f. ferrite coil 54 excited by an oscillator 58. As the detector moves in response to the changes in size of the film loop, the impedance of coil 62 is modified, which alters the speed of the motor 60 which drives the film transport shuttle 12. Thus this is driven faster or slower according to whether the loop becomes too small or too large. The oscillator 58 may additionally supply a h.f. bias to the recording head 32.

Title: Improvements in or relating to a printing press
IPC: B41F3/34
Filed: 1935-12-05
Abstract: 449,789. Printing-machines; feeding sheets. LOEW, T., 32, Kenmore Placo, Brooklyn, New York, U.S.A. Dec. 5, 1935, No. 33709. [Classes 100 (i) and 100 (ii)] A printing - machine is constructed of a travelling offset roller 36 or a roller provided with a printing-plate, which is moved across the top sheet of a pile, or across the top of a box, the roller being returned along a path which is raised out of printing position. As applied to an offset press the offset roller 36 receives its impression from a further roller 35, both rollers being mounted in a reciprocating truck 32 operated by a crank 44 and a pitman 42. The truck is guided by tracks in a carriage 29 suspended by links 30 which are oscillated by a link 46 operated by a lever 100 oscillated by a cam 104 on the shaft 45 of the crank 44. The links 30 cause the tracks to be at such levels that during the movement in one direction the roller 36 prints, and in the reverse direction the roller 35 receives an impression from type in a chase 23 which is inked by rollers 48 carried by the carriage 29 and receiving ink from a ratchet-rotated disc 27. When printing on a pile of sheets, the position of the pile is controlled by adjustable guides 56, 57, 58, which are clamped in the desired position on rods 60 supported by adjustable blocks carried on a cross-bar 66 (not shown). The pile is raised automatically by chains 75 which carry a pile support 54, and are operated by sprockets driven by worm gearing 112, 114 operated by a pawl-and-ratchet drive 115, 122, 130, 128 driven adjustably from the cam 104 by means of an oscillating lever 131 having a curved arm to which the link 130 is adjustably connected. The sheets are held during the printing operation by a pressing device 80 on an oscillating shaft operated from a shaft 170 by means of a flexible shaft 84. The shaft 170 is operated by the cam-and-link mechanism shown in Fig. 5, which also operates in a manner capable of adjustment, a suction separator 72 for removing the printed sheet from the pile. A lever 156 is oscillated by a cam 152 and operates toggle levers 162 connected by a slotted link 166 to a lever 168 on the shaft 170. The slotted link 166 engages a pin 178 on a geared sector 172 engaging a gear 196 on a shaft 188 mounted in blocks 184 adjustable along a bar 182. As the link 166 is raised by the cam 152 the shaft 188 is rotated and by means of yokes 190 and arms 192 a pair of suction caps 72 are moved to and from the pile and remove the top sheet.

Title: Improvements in or relating to a method for improving the strength of artificial insolubilised protein filaments
IPC: D01F4/00
Filed: 1947-12-22
Abstract: Artificial filaments obtained by wet-spinning protein solutions are subjected, after coagulation, to a hardening treatment by means of formaldehyde in the presence of an acidified highly concentrated salt solution and are subsequently subjected to treatment with an aqueous solution of an ionizable mercuric salt while held under tension so as to improve their tensile strength. For the hardening treatment there may be used a solution of formaldehyde in a concentrated salt solution which has been acidified with hydrochloric or sulphuric acid, or there may be used a concentrated solution of a hydrohalide salt containing formaldehyde or a substance capable of yielding formaldehyde, a salt of a reducing sulphur acid in which the atomic proportion of oxygen, if present, to sulphur does not exceed 2 : 1, and an acid which does not oxidize the salt of the sulphur acid, and which is substantially completely ionized in dilute aqueous solution. The mercuric salt solution may be mercuric acetate solution containing acetic acid; mercuric nitrate in dilute nitric acid; mercuric chromate in water; mercuric acetate solution with sufficient caustic soda to form a basic salt.  The filaments may be stretched to the maximum practical limit during the mercuric salt treatment.  The wet strength may be increased by as much as 200 per cent.  The treated filaments are of reduced diameter. They have reduced wet and dry elongations at break, and they have an increased weight which may be equivalent to the presence of 30 per cent of mercury.  The filaments may be obtained from alkaline solutions of casein or vegetable globulins, e.g. peanut or soya bean globulins.  In an example, coagulated filaments obtained from an alkaline solution of ground nut protein are hardened in a solution comprising brine, formalin, hydrochloric acid and sodium sulphide.  They are washed and dried, and then stretched to a maximum in a solution containing 3 per cent of mercuric acetate and 0.1 N acetic acid at 70 DEG  C. Specifications 513,910, and 533,952, are referred to.ALSO:Artificial filaments made from protein solutions and hardened by treatment with acidified saline solutions of formaldehyde, are subjected to treatment with an aqueous solution of an ionizable mercuric salt while held under tension.
